Abstract: A fiber optic lattice filter having a transfer function wherein the poles and zeros are adjustable independently of each other. The filter comprises a cascaded configuration of recursive (100) and non-recursive (102) fiber optic lattice filters. In one preferred embodiment, an all-pass fiber optic filter is formed by cascading all-pole and all-zero lattice filters, and by processing the resulting filtered output signal in a subtractive detection system (104). This detection system produces a signal which represents the difference between two signal outputs provided by the all-zero filter section, and which is adjustable in magnitude, thereby providing an overall filtering function which is capable of handling both positive and negative valued input signals.

Abstract: Electrolyte lost from a fuel cell, such as by evaporation, is replenished by introducing electrolyte from an external source into a reactant gas stream being delivered into the cell. The fresh electrolyte is vaporized or formed into droplets as it enters the cell such as by spraying the fresh electrolyte into the gas stream. If the electrolyte vapor pressure in the entering gas stream is made high enough, evaporation of the electrolyte from the cell can be halted or electrolyte can even be added to the cell from the gas stream.

Abstract: Known gas springs have the disadvantage that the valve required for setting the spring is difficult to produce and is thus expensive and that it also has a high space requirement. A further disadvantage is that the valve actuation is always effected from the end face opposite the piston rod, thus making the attachment of the gas spring difficult. These disadvantages are eliminated in that the valve is a slide valve which is arranged in the piston rod and can be operated through a longitudinal bore in the piston rod. <IMAGE>

Abstract: In the stepwise feeding of a packing material web for the application of cover strips over prepunched pouring openings, the pouring opening is sensed by means of a photocell which is located as long before the point of application as the distance between two pouring openings. Any errors in this distance will thus affect the accuracy of application. In order to avoid this it is proposed in accordance with the invention to sense the passage of the actual pouring opening and start a countdown sequence, at the end of which the web feed is interrupted with the pouring opening in correct position for the application of the cover strip. An arrangement for the realization of this, seen in the direction of feed of the material web (1),comprises a sensing device (4), a processing device (5) and a forward feeding device (9) which are connected to a control unit (13)

Abstract: A technique is disclosed for the detection of cancer using nuclear magnetic resonsance (NMR). Specifically, NMR parameters for protons of lipid methyl and/or methylene groups are determined and compared against a corresponding value for healthy patients. In the pre­ferred embodiments, an NMR spectrometer is employed in conjunction with a Fourier transformer to provide a spectrum for non-water components of blood, blood serum or blood plasma and the width of the methyl and/or methylene groups is measured at half-height as a determination of spin-spin relaxation time (T₂) which is the parameter used for purposes of comparison with healthy controls. Suppres­sion of the water proton signal is employed where necessary in order to obtain a suitable spectrum for the non-water component protons.

Abstract: A circuit arrangement for the selective control of functional modules (15) should be designed for providing for a rapid and liberal selection of individual ones of the functional modules (15) or particular module groups with little requirement for data transmission with little circuit expenditure for a bus system (XY). For this purpose, it is preferably provided to connect matrix column lines (Xi) and row lines (Yi) via signal transmitters in the form of interrupter switches (13xi, 13yi) to the supply lines (X, Y) of a central power source (12) and to feed the functional modules (15ij) via the areas of intersection (ij) of the matrix lines (Xi, Yj). When the circuit to the power source (12) is interrupted for a short time at a time- defined interval (ij) on one matrix line (Xi) and on the other matrix line (Yj), this selects exactly the functional module (15ij) which is switched on via this area of intersection (ij) and interrogates the second supply interruption after exactly this time interval (tij). A transmission of data from the functional module (15ij) to a connected computer is possible by means of a method of the same type. <IMAGE>

Abstract: The training apparatus has a spring arrangement. It is proposed that, after a certain first path (13), a movable part (7), which is loaded by a first spring arrangement, carries along a second spring arrangement (12) over a stop so that, in a further deflection path of the movable part (7), the summated spring forces of both spring elements (10, 12) have to be overcome by the exercising person. Thus, corresponding to a dynamic force, the training of a fast sequence of movement is enhanced with intense muscle tension at the end of the sequence of movement. <IMAGE>

Abstract: A compressed air system (10) includes an air compressor (12) the inlet of which is communicated to the vehicle engine turbocharger. The outlet of the air compressor is communicated through an air dryer (22) to a storage reservoir (26). A governor (28) is responsive to the pressure level in the reservoir (26) to generate an unloading signal unloading the air compressor (12) when the pressure in the reservoir (26) attains a predetermined value. The unload­ing signal is also communicated through a control valve (34, 38) to purge the air dryer during compressor unloading. The control valve closes communication between the governor (28) and the air dryer (22) to trap a predetermined pressure level in the purge volume of the air dryer (22) to prevent the air dryer from purging to atmospheric pressure. Accordingly, a predetermined air pressure level is maintained in the purge volume, so that the outlet of the turbocharger can never be communicated to atmospheric pressure.

Abstract: A SYSTEM FOR RELEASING AN ANCHOR MOORED TO THE BOTTOM OF THE SEA, based on a mechanical device being inserted bet­ween the lower end of the anchor suspension chain or cable (57) and the upper part of the arm of the anchor (56). Said mechanical device basically comprises two in-between articulated parts (1, 2), which, in their normal position,are blocked in order to form a single body for attaching the above-mentioned lower end of the anchor suspension cable (57) to the upper end of said anchor arm. By means of an additional and independent accessory or piece which is made to slide along the very anchor suspension cable, both parts (1, 2) of the device are unblocked, by tractioning said additional and independent piece. Said unblocking implies that one (1) the parts of the device will be only attached to the lower end of the suspension cable (57), whilst the other part (2) will be attached to the upper end of the anchor arm, all that so that the tractioning force for raising the anchor will be exerted from the lower part thereof, i.e., in a sense prac­tically opposite to the axle of the plane formed by the claws or bills of said anchor. Said way of tractioning the anchor is achieved by virtue of the fact that between said lower ba­se of the anchor and the part being attached when unblocking to the lower end of the suspension cable (57), a small chain (37) is fixed.

Abstract: A multiple recess isolation technology avoids stress induced defects while providing a substantially planar surface. A silicon substrate (10) is patterned and etched, creating active moat regions (18) and recesses (20a-b and 21a-b). The recesses are filled with oxide by growing a field oxide (40) in wide recessed regions (21) using a LOCOS process, while depositing a planarization field oxide (44) in narrow recessed regions (20). After etching the structure to obtain a planar surface, standard procedures are used to fabricate the active devices. The process uses a single photolithographic masking step and results in only a very small loss of the width electrically active regions.
